The Temperature This Morning Was -2.3°C. If The Temperature Drops 1.3°C Every Day, What Will The Temperature Be 1 Week From Now?
Introduction
The temperature this morning was -2.3°C, and it's expected to drop by 1.3°C every day. As we try to predict the temperature 1 week from now, we'll delve into the world of mathematics to find the solution. In this article, we'll explore the concept of linear equations and how they can be used to model real-world scenarios.
Understanding the Problem
The problem states that the temperature drops by 1.3°C every day. To find the temperature 1 week from now, we need to calculate the total drop in temperature over 7 days. Since the temperature drops by 1.3°C every day, we can represent this as a linear equation:
T(t) = T0 - rt
where:
- T(t) is the temperature at time t
- T0 is the initial temperature (in this case, -2.3°C)
- r is the rate of change (in this case, -1.3°C/day)
- t is the time in days
Calculating the Temperature Drop
To find the temperature 1 week from now, we need to calculate the total drop in temperature over 7 days. We can do this by multiplying the rate of change (r) by the number of days (t):
ΔT = r × t = -1.3°C/day × 7 days = -9.1°C
Finding the Temperature 1 Week from Now
Now that we have the total drop in temperature, we can find the temperature 1 week from now by subtracting the drop from the initial temperature:
T(7) = T0 - ΔT = -2.3°C - (-9.1°C) = -2.3°C + 9.1°C = 6.8°C
Conclusion
In this article, we used the concept of linear equations to model the temperature drop over 7 days. By understanding the problem and using the formula for linear equations, we were able to calculate the temperature 1 week from now. The result shows that the temperature will be 6.8°C, a significant drop from the initial temperature of -2.3°C.
Real-World Applications
